TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM II. McPHEnsoN, of Danby, Tompkins county, New York, have invented cern. tain Improvements in Horse-Rakes; and I do hereby declare that the following is a full and exact description thereof, reference'being had to the annexed drawings, and to the letters marked thereon.

My objects are, first, to simplify and make eicient a revolving rake-head; second, to cause one or both wheels to revolve the rake; third, to stop and hold the teeth to their work with great accuracy; and fourth, so control the whole working of the rake easily by a simple and peculiar' lever, and its associated parts, and malte it automatic. The first object I accomplish by putting the wheel axle through an ovalshapcd head, and cuttinng grooves near the angles ofthe oval, and in thc grooves inserting a rod on which the teeth are fastened by coils, and holding the rod and teeth in the grooves by staples er other means; the second by fastening to the head a cog-wheel, which gears into a second Wheel, 'which has a wider face and an end play to its journals, so that it locks and unlocks to and from a third wheel on the rake-wheel; the third by making a lever, which locks and unlocks the wheels just named, do the further duty of engaging in the cam or other device usually on the cogwheel on the rake-head; and fourth, by the arrangement of the lever which operates the rake; this is seen in the drawings, which are*- Figure I, a longitudinal section.

Figure 2, a transverse section, and

Figure 3, enlarged views of the head, and the cam on it.

In fig. l, A-is the rake-head on its axle, with two sets of teeth in the grooves, fastened by rods and staples, with the pressure staplcsabout the teeth; and B is the first, C the second, and D the third whecls,'and E the lever with its fulcrum on the cross-piece F, with two points of action, one at G, on the cam on the pivot-wheel or near it, and the other at G on the journal of the second wheel; and H is the front beam, and I thc rear beam of the frame connected by the side beams J. The strippers K project from the piece or beam I. I

In iig. 2 one set of teeth only is used.

The same letters and explanations refer to the same parts.

The lever E has thrown the second and third wheels out of gear and is holding the teeth to the ground by its lower end in the depression in the cam at G, marked L. Then two sets of teeth are used the lever enters alternate depressions L and M; and O are the coils about the groove rod held by thc staples I?. The pressure staples Q enclose the teeth' on the upper part of the rake-head; and R is the spring that makes the action of the lever Eautomatic on the cam L M.

In fig. 3 the letters, parts, and explanations are the same as given.

The devices I use are apparent to those skilled in the art to which it appel-talus.

Claim.

1.. I claim the oval revolving head A, provided with the groove or grooves O, the rod for holding the teeth and the pressure staples Q, as described. v

2. I claim the combination of the lever E, made as described, the spring R and stop-plate L, substantially as and for the purposes described.

3. claim the wheels B, C, D, and lever E, all constructed and arranged substantially as described.

Y WILLIAM H. MCPHERSON.
